The lines are elevated, not subway. Between Hove Beach station and Schottler station the eastern track has a side track that goes to little rail yard. Between Huntington Street station and Francis International Airport subway terminal there is an extension connected by a T-juction. This extension has one station called Dukes Boulevard Station. This extension ends after station and is not served by the LTA trains, since it has been temporary shut down for maintenance.

Immediately after departing Hove beach, Route 8 services change to Route A for the Algonquin Outer Line with a corresponding announcement of "This is the A train, the enxt stop is Easton station."

Like the counterparts of the J/3 lines, Manganese East is the first stop where Northbound J trains for the Algonquin Outer Line are referred to. As a north-by-westbound Route 3 service prepares to depart Huntington Street Lower Level Station, an announcement will play saying "This is the J train, the next stop is Manganese East station," followed by the stantard door chime and departure.
